The countdown to #BabyWilson is officially on! While we don't know the gender of the little one yet, that's not stopping the couple from celebrating it's arrival tenfold! E! News just reported that the Wilsons celebrated last weekend with a co-ed baby shower.

E! reports that the all-white celebration was planned by Mindy Weiss, catered by Shake Shack, and all the ladies (like famous friends Lala Anthony and Serena Williams) wore flower crowns.

The couple announced they were expecting in October, but since then have kept mum on the gender. The other day, Ciara posted a photo of one of her pregnancy outfits, with the caption "Blue is one of my favorite colors..." which sent the internet into a flurry that the littlest Wilson would be a boy. Ciara already has a son with ex, rapper Future. This will be Russell's first child.
